To support sustainable urban mobility strategies, reallocating road space from private vehicles to other uses may be a relevant intervention. Novel empirical knowledge could reduce barriers for implementing such interventions. A planned, 14-month capacity reduction of a main road tunnel in Oslo, Norway, carrying 70,000 vehicles a day, offered an excellent opportunity to document how commuters adapted, and what effects and consequences they experienced. Analyses of traffic data were combined with surveys and interviews with commuters. Congestion increased in the tunnel and on adjacent road-links, although road users adapted in ways resulting in significant traffic reduction through the tunnel. Some employees in an area near the tunnel experienced increased time-usage on their commute, and some adapted by changing transport mode, route, or trip-timing. However, results showed that they did not experience major negative consequences. Few commuters reported a need to shift routines in the household, and commuter satisfaction remained high.

为了支持可持续的城市交通策略，将道路空间从私家车重新分配到其他用途可能是一项相关的干预措施。新的经验知识可以减少实施此类干预措施的障碍。挪威奥斯陆的一条主要公路隧道计划进行14个月的产能缩减，每天可运载70,000辆汽车，这为记录通勤者的适应方式以及他们受到的影响和后果提供了极好的机会。交通数据分析与通勤者的调查和访谈相结合。尽管道路使用者以某种方式进行了调整，导致通过隧道的交通量大大减少，但隧道和相邻道路连接处的拥堵加剧了。在隧道附近区域的一些员工通勤时间增加了，而有些则通过改变运输方式，路线，或旅行时机。但是，结果表明他们没有遇到重大的负面后果。很少有通勤者报告需要改变家庭常规，通勤者的满意度仍然很高。
